A 44-year-old woman presents with a bilateral throbbing headache and nausea that was preceded by vision changes of flashing ligh

ts and blind spots. Her past medical history is significant for poorly controlled hypertension. Currently, her blood pressure is 182/100 and neurological examination is normal. CT scanning reveals no intracranial pathology. Which of the following is the most appropriate headache treatment at this time?A. High flow oxygen
B. Ibuprofen
C. Sumatriptan alone
D. Sumatriptan plus ergotamine

Answer: High flow O2 is best. It is used with those persons who present with severe cluster headache or migraine; the triptan is contraindicated by her B.P., Ibuprofen would not be very useful with presentation of aura and bilateral nature of her headache; ergotamine is surely contraindicated given her history.

Step2247 [10]
<span>The abundance and variety of fossils in Phanerozoic rocks have allowed geologists to decipher in considerable detail the past 600 million years or so of the Earth’s history. In Precambrian rocks, however, fossils are rare; thus, the geologic record of this important part of the Earth’s history has been especially difficult to decipher. Nonetheless, stratigraphy and radiometric dating of Precambrian rocks have clearly demonstrated that the history of the Earth extends billions of years into the past.</span>

The best way to measure an exact volume is with a(n) _____________.
xxTIMURxx [149]
The answer is E, graduated cylinder.

Meanwhile beaker and test tubes may have markings, but they're not as accurate. Especially in beakers, their wide diameter only makes an approximate volume, as it is very likely to have a reading mistake on that. Their main function is not to measure volumes, thus there marking may already have an mistake.

And in watch glass and evaporating dish, they're both very shallow and wide in diameter too, so they're not for measuring volumes. Plus, not all of them have markings.

And in graduated cylinder, the thin shape makes the reading a lot more accurate and the main purpose for that is to measure volumes. They also come in transparent tubes that can make the reading clear and easy to read.

The length of linker DNA segments varies somewhat among organisms. The length of the linker DNA in sea urchin is 110 base pairs.
nasty-shy [4]

Answer:

362 nucleosomes

Explanation:

A nucleosome repeat is made up of the DNA (146 bp) wrapped around the core nucleosome particle and the linker DNA (110 bp as in this situation). We can conclude that, every repeat stands for 256 (146 + 110) base pairs of DNA.

We are given the length of the entire region to be 92,672 bp long,

To determine the number of nucleosomes to organize the region into the 10nm fiber structure

Let,

Number of nucleosomes =

the length of the entire region

------------------- -----

base pairs of DNA.

= 92,672

-------

256

= 362 nucleosomes

Therefore, 362 nucleosomes is needed to structure the region into the 10nm fiber structure.
